WILLIAM W. WALLACE, OF KNOXVILLE, TENNESSEE.

CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 791,518, dated June 6, 1905. Application filed September l2, 1904. Serial No. 224,140.

To all whom it may concern,.-

Beit known that I, WILLIAM W. WALLACE, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented a new and useful Improvement in Car-Axle Boxes, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates particularly to means for closing the front opening of car-axle boxes.

The object of the invention is to provide a construction adapted to close automatically in order that the box may not remain open through the neglect of persons -who inspect car-axle boxes and provide the same with oil and cotton-Waste.

A further object of the invention is to provide a construction Which is simple and cheap.

A further object of the invention is to provide a lid or door which may be attached without bolts, keys, or other similar devices, to the end that in the event of breakage a neW door can be readily put into place.

In the accompanying drawings, Figure l is a plan of a car-axle box embodying my improvement. Fig. 2 is a side elevation of the same box. Fig. 3 isa sectional side elevation of the same box. Fig. 4: is a front elevation. Fig. 5 is a vertical transverse section .on the linel 5 5 of Fig. 3. Fig. 6 is aplan of the door or lid. Fig. 7 is a sectional detail view of a modiiication of one of the arms of the door or lidlland the adjacent portion of the upright W3.

In the particular form shown in the drawings the box is rectangular 'in cross-section, as shown in Fig. 5, 1 being the upper horizontal wall, and 2 2 being the lateral upright walls, and 3 being the bottom wall. At the front the lower portions of the lateral walls are joined by a front wall 4. Between this wall and the lateral walls and the upper wall is the outer opening or port of the car-axle y box, through which the interior of the box door is free to move upward. movement 1s, however, so limlted that the The upper outer portion of the lip 7, which bears against said shoulder-1a when the door is in its normal position, whereby the door is held against further down- Ward movement. Thelower edge of said door extends a little way below the upper edge of the front'wall 4. At each lateral edge of the door there is an inward-directed iiange 8, extending a short distance over the outer face of the adjacent lateral wall 2. Thus the door is adapted to completely close the outer opening of the box. From each such flange 8 an arm 9 extends along the adjacent lateral wall and bears a lug or journal 10, extending into the adjacent socket or bearing 5. Thus the lid or door is adapted to move through an arc upon the axis of said bearings. As already indicated, the engagement between the iiange 7 and the shoulder 1 prevents the downward movement of the door beyond the position shown by solid lines in Figs. 2 and 3; but said Such upward greater portion of the weight of said lid must always remain outside of an upright plane cutting the axis upon which said door turns. For this purpose the ribs 11 may be so placed as to form stops for the arms 9. Hence said lid cannot be so set as to need manual closing after it has been opened for the inspection of v said door, its arms, and its journals are pref-- erably an integral casting, the arms being made liexible to a suiiicient degree to permit lateral springing until the journals enter the bearings. Said journals and said bearings are adapted to be formed suiiiciently accurate IOO by casting to render subsequent v machinework unnecessary, and no bolts, keys, or other similar devices are needed for attaching the door, and if a door breaks a new one may be readily sprung into place.

While the front wall 4 is shown concentric with the axis of the journals, said wall may be of any desired form, and while the upper portion of the front end of the box is shown concentric with said axis it is to be observed that said end may be of other form, provided the form of the lid or door corresponds and allowance is made for the upward movement of the door.

The journals and the bearings for the door or lid may be interchanged, the journals being made to extend outward from the outer faces of the` walls 2, while the bearings extend into or through the arms, as shown in Fig. 7, wherein 12 is the journal and 13 is the bearing.

I claim as my invention- 1. The combination with acar-axle box having a front opening and lateral and upper and lower walls. the upper wall being provided with a shoulder, 1, of a door adapted to extend over said opening and having a flange to engage said shoulder and having integral, fiexible arms, said arms and said lateral walls being provided with interengaging journals and bearings integral with said arms and wall, substantially as described.

2. The combination with a car-axle box having a front opening and lateral and upper and lower walls, the lateral walls being provided with hinge-bearings and the upper wall being provided with a shoulder, 1, of a door adapted to extend over said opening and having a flange to engage said shouldei` and having integral arms provided with journals extending into said bearings, substantially as described.

3. The combination with acar-axle box having a front opening and lateral and upper and lower walls, the lateral walls being provided with hinge-bearings and the upper wall being provided with a shoulder, 1, of a door resting over said opening and having a iiange to engage said shoulder and having lateral iianges and integral arms provided with journals extending into said bearings, substantially as described.

In testimony whereof I have signed my name, in presence of two witnesses, this 31st day of August, in the year 1904:.

WILLAM W. WALLACE.
